Concept Introduction:
Standard state condition:
The electromotive force (EMF) is the maximum potential difference between two electrodes of a galvanic or voltaic cell. This quantity is related to the tendency for an element, a compound or an ion to acquire (gain) or release (loss) electrons.
Half-cell Reaction: A half-cell is one of the two electrodes in a galvanic cell or simple battery.
Example, the Zn-Cu battery, the two half cells make an oxidizing couple.
Standard state condition are defined as by standard temperature &pressure (STP) with a temperature of
At STP (Standard Temperature &Pressure) 1mole of ideal gas occupied 22.4L.
